2. Description of the Related Art

Numerous cell surface receptors use one or more of the mitogen-activated protein kinase (MAP kinase) cascades during signal transduction. MAP kinases are a family of protein-directed serine/threonine kinases that are activated by dual phosphorylation. One subgroup of the MAP kinases is p38 MAP kinase, which is activated by a variety of signals including proinflammatory cytokines such as tumor necrosis factor (TNF) and interleukin-1 (IL-1), as well as bacterial lipopolysaccharides and environmental stress such as osmotic shock and ultraviolet radiation (Ono, K. and J. Han, Cell Signal. 12: 1, 2000). Within the p38 kinase family, there are four distinct isozymes: p38 alpha, p38 beta, p38 gamma, and p38 delta. The p38 kinase family function downstream of an activating stimulus by phosphorylating and activating transcription factors (e.g. ATF2, CHOP and MEF2C) as well as other kinases (e.g. MAPKAP-2 and MAPKAP-3) (Trends in Cell biology 7, 353–361, 1997; Mol Cell Biology 19, 21–30, 1999; EMBO J 20, 466–479, 2001) Upon activation, the p38 kinase cascade leads to the induction of gene expression of several factors involved in inflammation and immunity including TNF, interleukin-6, granulocyte-macrophage colony stimulating factor (GM-CSF), and HIV long terminal repeat (Paul et al., Cell Signal. 9: 403–410, 1997). The products of the p38 phosphorylation stimulate the production of inflammatory cytokines and other proteins, including TNF and IL-1, and cyclooxygenase-2, and also possibly modulate the effects of these cytokines on their target cells, and thus stimulate inflammation processes (Lee, J. C. et al, Nature, 372: 376, 1994).

P38 MAP kinases have also been shown to promote apoptosis during ischemia in cardiac myocytes, which suggests that p38 MAP kinase inhibitors can be used to treat ischemic heart disease (J. Biol. Chem. 274, 6272, 1999). They are also required for T-cell HIV-1 replication and may be useful targets for AIDS therapy. P38 pathway inhibitors have been used to increase cancer cell sensitivity to cancer therapy also find use in the treatment of asthma (JPET 293, 281, 2000).

TNF is a cytokine and a potent proinflammatory mediator implicated in inflammatory conditions such as arthritis, asthma, septic shock, non-insulin dependent diabetes mellitus, multiple sclerosis, asthma, and inflammatory bowel disease. Thus inhibitors of p38 MAP kinases (required for TNF production) may be useful for the treatment of inflammatory conditions resulting from excessive cytokine production such as arthritis. (Boehm, J. C. and J. L. Adams, Exp. Opin. Ther. Patents 10: 25, 2000, and references cited therein). TNF has also been implicated in viral infections, such as HIV, influenza virus, and herpes virus including herpes simplex virus type-1 (HSV-1), herpes simplex virus type-2 (HSV-2), cytomegalovirus (CMV), varicella-zoster virus (VZV), Epstein-Barr virus, human herpesvirus-6 (HHV-6), human herpesvirus-7 (HHV-7), human herpesvirus-8 (HHV-8), pseudorabies and rhinotracheitis, among others.

Excessive or unregulated TNF production has also been shown to produce elevated levels of IL-1. Inhibition of TNF, therefore, should reduce levels of IL-1 (European Cytokine Netw 6, 225, 1995) and ameliorate disease states caused by unregulated IL-1 synthesis. Such disease states include rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis, sepsis, septic shock, endotoxic shock, gram negative sepsis, toxic shock syndrome, adult respiratory distress syndrome, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcosis, bone resorption diseases, reperfusion injury, graft versus host reaction, alallograft rejections, fever and myalgias due to infection, cachexia secondary to infection or malignancy, cachexia secondary to acquired immune deficiency syndrome (AIDS), AIDS related complex (ARC), keloid formation, scar tissue formation, Crohn's disease, ulcerative colitis, and pyresis.

IL-1 has also been shown to mediate a variety of biological activities such as the activation of T-helper cells, induction of fever, stimulation of prostaglandin or collagenase production, neutrophil chemotaxis, and the suppression of plasma iron levels (Rev. Infect. Disease, 6, 51 (1984)). Elevated levels of IL-1 have also been implicated in mediating or exacerbating a number of disease states including rheumatoid arthritis, osteoarthritis, rheumatoid spondylitis, gouty arthritis, inflammatory bowel disease, adult respiratory distress syndrome (ARDS), psoriasis, Crohn's disease, ulcerative colitis, anaphylaxis, muscle degeneration, cachexia, Reiter's syndrome, type I and type II diabetes, bone resorption diseases, ischemia reperfusion injury, arteriosclerosis, brain trauma, multiple sclerosis, sepsis, septic shock, and toxic shock syndrome. Viruses sensitive to TNF inhibition, such as HIV-1, HIV-2, HIV-3, are also affected by IL-1 production. In rheumatoid arthritis, both IL-1 and TNF induce collagenase synthesis and ultimately lead to tissue destruction within arthritic joints (Lymphokine Cytokine Res. (11): 253–256, (1992) and Clin. Exp. Immunol. 989:244–250, (1992)).

IL-6 is another pro-inflammatory cytokine, which is associated with many conditions including inflammation. Consequently, TNF, IL-1 and IL-6 affect a wide variety of cells and tissues and are important inflammatory mediators of a wide variety of disease states and conditions. The inhibition of these cytokines by inhibition or modulation of p38 kinase is of benefit in controlling, reducing and alleviating many of these disease states and conditions. Therefore, the invention concerns finding small molecule inhibitors or modulators of p38 kinase and the p38 kinase pathway.

As TNF-beta has close structural homology with TNF-alpha (also known as cachectin), and since each induces similar biologic responses and binds to the same cellular receptor, the synthesis of both TNF-alpha and TNF-beta are inhibited by the compounds of the invention and thus are herein referred to collectively as “TNF” unless specifically delineated otherwise.

Compounds of invention include the compounds of Formula I and their corresponding pharmaceutically acceptable acid and base addition salts. If the compound of the invention is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, particularly a pharmaceutically acceptable acid addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing such addition salts from base compounds.

Non-toxic pharmaceutically acceptable salts include, but are not limited to salts of inorganic acids such as hydrochloric, sulfuric, phosphoric, diphosphoric, hydrobromic, and nitric or salts of organic acids such as formic, citric, malic, maleic, fumaric, tartaric, succinic, acetic, lactic, methanesulfonic, p-toluenesulfonic, 2-hydroxyethylsulfonic, salicylic and stearic. Similarly, pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium and ammonium. Those skilled in the art will recognize a wide variety of non-toxic pharmaceutically acceptable addition salts.

The compounds of this invention may contain one or more asymmetric carbon atoms, so that the compounds can exist in different stereoisomeric forms. These compounds can be, for example, racemates, chiral non-racemic mixtures or mixtures of diastereomers. In these situations, the single enantiomers, i.e., optically active forms, can be obtained by asymmetric synthesis or by resolution of the racemates or mixtures. Resolution of the racemates can be accomplished, for example, by conventional methods such as crystallization in the presence of a resolving agent; chromatography, using, for example a chiral HPLC column; or derivatizing the racemic mixture with a resolving reagent to generate diastereomers, separating the diastereomers via chromatography or selective crystallization, and removing the resolving agent to generate the original compound in enantiomerically enriched form. Any of the above procedures can be repeated to increase the enantiomeric purity of a compound.

The compounds of the invention may exist as atropisomers, i.e., chiral rotational isomers. The invention encompasses the racemic and the resolved atropisomers. The following illustration generically shows a compound (Z) that can exist as atropisomers as well as its two possible atropisomers (A) and (B). This illustration also shows each of atropisomers (A) and (B) in a Fischer projection. In this illustration, R₁, R₂, and R₄ carry the same definitions as set forth for Formula I, R_(p′) is a substituent within the definition of R₅, and R_(p) is a non-hydrogen substituent within the definition of R₅.

When the compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, and unless otherwise specified, it is intended that the compounds include the cis, trans, Z- and E-configurations. Likewise, all tautomeric forms are also intended to be included.

The compounds of general Formula I may be administered orally, topically, parenterally, by inhalation or spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes percutaneous, subcutaneous, intravascular (e.g., intravenous), intramuscular, or intrathecal injection or infusion techniques and the like. In addition, there is provided a pharmaceutical formulation comprising a compound of general Formula I and a pharmaceutically acceptable carrier. One or more compounds of general Formula I may be present in association with one or more non-toxic pharmaceutically acceptable carriers and/or diluents and/or adjuvants, and if desired other active ingredients. The pharmaceutical compositions containing compounds of general Formula I may be in a form suitable for oral use, for example, as tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsion, hard or soft capsules, or syrups or elixirs.

For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, hard or soft capsule, lozenges, dispensable powders, suspension, or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are tablets or capsules.

Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preservative agents in order to provide pharmaceutically elegant and palatable preparations. Tablets contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients that are suitable for the manufacture of tablets. These excipients may be for example, inert diluents, such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, corn starch, or alginic acid; binding agents, for example starch, gelatin or acacia, and lubricating agents, for example magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques. In some cases such coatings may be prepared by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monosterate or glyceryl distearate may be employed.

Formulations for oral use may also be presented as hard gelatin capsules, wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate, or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, for example peanut oil, liquid paraffin or olive oil.

Formulations for oral use may also be presented as lozenges.

Aqueous suspensions contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients are suspending agents, for example sodium carboxymethylcellulose, methylcellulose, hydropropyl-methylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally-occurring phosphatide, for example, lecithin, or condensation products of an alkylene oxide with fatty acids, for example polyoxyethylene stearate, or condensation products of ethylene oxide with long chain aliphatic alcohols, for example heptadecaethyleneoxycetanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example polyethylene sorbitan monooleate. The aqueous suspensions may also contain one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose or saccharin.

Oily suspensions may be formulated by suspending the active ingredients in a vegetable oil, for example arachis oil, olive oil, sesame oil, or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent, for example beeswax, hard paraffin, or cetyl alcohol. Sweetening agents and flavoring agents may be added to provide palatable oral preparations. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.

Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents or suspending agents are exemplified by those already mentioned above. Additional excipients, for example sweetening, flavoring, and coloring agents, may also be present.

Pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil or a mineral oil or mixtures of these. Suitable emulsifying agents may be naturally-occurring gums, for example gum acacia or gum tragacanth, naturally-occurring phosphatides, for example soy bean, lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides, for example sorbitan monooleate, and condensation products of the said partial esters with ethylene oxide, for example polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavoring agents.

Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol, glucose or sucrose. Such formulations may also contain a demulcent, a preservative, and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents that have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parentally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The compounds of general Formula I may also be administered in the form of suppositories, e.g., for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient that is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials include cocoa butter and polyethylene glycols.

Compounds of general Formula I may be administered parenterally in a sterile medium. The drug, depending on the vehicle and concentration used, can either be suspended or dissolved in the vehicle. Advantageously, adjuvants such as local anesthetics, preservatives, and buffering agents can be dissolved in the vehicle.

The active ingredient may also be administered by injection (IV, IM, subcutaneous or jet) as a composition wherein, for example, saline, dextrose, or water may be used as a suitable carrier. The pH of the composition may be adjusted, if necessary, with suitable acid, base, or buffer. Suitable bulking, dispersing, wetting or suspending agents, including mannitol and PEG 400, may also be included in the composition. A suitable parenteral composition can also include a compound formulated as a sterile solid substance, including lyophilized powder, in injection vials. Aqueous solution can be added to dissolve the compound prior to injection.

For disorders of the eye or other external tissues, e.g., mouth and skin, the formulations are preferably applied as a topical gel, spray, ointment or cream, or as a suppository, containing the active ingredients in a total amount of, for example, 0.075 to 30% w/w, preferably 0.2 to 20% w/w and most preferably 0.4 to 15% w/w. When formulated in an ointment, the active ingredients may be employed with either paraffinic or a water-miscible ointment base.

Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example at least 30% w/w of a polyhydric alcohol such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol and mixtures thereof. The topical formulation may desirably include a compound, which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethylsulfoxide and related analogs. The compounds of this invention can also be administered by a transdermal device. Preferably topical administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety. In either case, the active agent is delivered continuously from the reservoir or microcapsules through a membrane into the active agent permeable adhesive, which is in contact with the skin or mucosa of the recipient. If the active agent is absorbed through the skin, a controlled and predetermined flow of the active agent is administered to the recipient. In the case of microcapsules, the encapsulating agent may also function as the membrane. The transdermal patch may include the compound in a suitable solvent system with an adhesive system, such as an acrylic emulsion, and a polyester patch. The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier, which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make-up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base, which forms the oily, dispersed phase of the cream formulations. Emulsifiers and emulsion stabilizers suitable for use in the formulation of the invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, and sodium lauryl sulfate, among others. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used.

Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredients are dissolved or suspended in suitable carrier, especially an aqueous solvent for the active ingredients. The anti-inflammatory active ingredients are preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5% w/w. For therapeutic purposes, the active compounds of this combination invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art.

The amount of therapeutically active compounds that are administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the severity of the inflammation or inflammation related disorder, the route and frequency of administration, and the particular compound employed, and thus may vary widely. The pharmaceutical compositions may contain active ingredients in the range of about 0.1 to 1000 mg, preferably in the range of about 7.0 to 350 mg. A daily dose of about 0.01 to 100 mg/kg body weight, preferably between about 0.1 and about 50 mg/kg body weight and most preferably between about 0.5 to 30 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day. In the case of skin conditions, it may be preferable to apply a topical preparation of compounds of this invention to the affected area two to four times a day.

It will be understood, however, that the specific dose level for any particular patient will depend upon a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, and rate of excretion, drug combination and the severity of the particular disease undergoing therapy.

For administration to non-human animals, the composition may also be added to the animal feed or drinking water. It may be convenient to formulate the animal feed and drinking water compositions so that the animal takes in a therapeutically appropriate quantity of the composition along with its diet. It may also be convenient to present the composition as a premix for addition to the feed or drinking water.

The disclosures in this application of all articles and references, including patents, are incorporated herein by reference.

Biological Evaluation

p38 Kinase Assay

Cloning of Human p38a:

The coding region of the human p38a cDNA is obtained by PCR-amplification from RNA isolated from the human monocyte cell line THP.1. First strand CDNA is synthesized from total RNA as follows: 2 μg of RNA is annealed to 100 ng of random hexamer primers in a 10 μl reaction by heating to 70° C. for 10 minutes followed by 2 minutes on ice. cDNA is then synthesized by adding 1 μl of RNAsin (Promega, Madison Wis.), 2 μl of 50 mM dNTP's, 4 μl of 5× buffer, 2 μl of 100 mM DTT and 1 μl (200 U) of Superscript II™ AMV reverse transcriptase. Random primer, DNTP's and Superscript II™ reagents are all purchased from Life-Technologies, Gaithersburg, Mass. The reaction is incubated at 42° C. for 1 hour. Amplification of p38 cDNA is performed by aliquoting 5 μl of the reverse transcriptase reaction into a 100 μl PCR reaction containing the following: 80 μl dH.sub.2 O, 2. μl 50 mM dNTP's, 1 μl each of forward and reverse primers (50 pmol/μl), 10 μl of 10× buffer and 1 μl Expand™ polymerase (Boehringer Mannheim). The PCR primers incorporated Bam HI sites onto the 5′ and 3′ end of the amplified fragment, and are purchased from Genosys. The sequences of the forward and reverse primers were SEQ ID 1: 5′-GATCGAGGATTCATGTCTCAGGAGAGGCCCA-3′ and SEQ ID 2: 5′GATCGAGGATTCTCAGGACTCCATCTCTTC-3′ respectively. The PCR amplification is carried out in a DNA Thermal Cycler (Perkin Elmer) by repeating 30 cycles of 94° C. for 1 minute, 60° C. for 1 minute and 68° C. for 2 minutes. After amplification, excess primers and unincorporated dNTP's is removed from the amplified fragment with a Wizard™ PCR prep (Promega) and digested with Bam HI (New England Biolabs). The Bam HI digested fragment is ligated into BamHI digested pGEX 2T plasmid DNA (PharmaciaBiotech) using T-4 DNA ligase (New England Biolabs) as described by T. Maniatis, Molecular Cloning: A Laboratory Manual, 2nd ed. (1989). The ligation reaction is transformed into chemically competent E. coli DH10B cells purchased from Life-Technologies following the manufacturer's instructions. Plasmid DNA is isolated from the resulting bacterial colonies using a Promega Wizard™ miniprep kit. Plasmids containing the appropriate Bam HI fragment are sequenced in a DNA Thermal Cycler (Perkin Elmer) with Prism™ (Applied Biosystems Inc.). cDNA clones are identified that coded for both human p38a isoforms (Lee et al. Nature 372, 739). One of the clones that contained the cDNA for p38a-2 (CSB-2) inserted in the cloning site of PGEX 2T, 3′ of the GST coding region is designated pMON 35802. The sequence obtained for this clone is an exact match of the cDNA clone reported by Lee et al. This expression plasmid allows for the production of a GST-p38a fusion protein.

Expression of Human p38a

GST/p38a fusion protein is expressed from the plasmid pMON 35802 in E. coli, stain DH10B (Life Technologies, Gibco-BRL). Overnight cultures are grown in Luria Broth (LB) containing 100 mg/ml ampicillin. The next day, 500 ml of fresh LB is inoculated with 10 ml of overnight culture, and grown in a 2 liter flask at 37° C. with constant shaking until the culture reached an absorbance of 0.8 at 600 nm. Expression of the fusion protein is induced by addition of isopropyl b-D-thiogalactosidase (IPTG) to a final concentration of 0.05 mM. The cultures are shaken-for three hours at room temperature, and the cells are harvested by centrifugation. The cell pellets are stored frozen until protein purification.

Purification of P38 Kinase-Alpha

All chemicals are from Sigma Chemical Co. unless noted. Twenty grams of E. coli cell pellet collected from five 1 L shake flask fermentations is resuspended in a volume of PBS (140 mM NaCl, 2.7 mM KCl, 10 mM Na.sub.2 HPO.sub.4, 1.8 mM KH.sub.2 PO.sub.4, pH 7.3) up to 200 ml. The cell suspension is adjusted to 5 mM DTT with 2 M DTT and then split equally into five 50 ml Falcon conical tubes. The cells are sonnicated (Ultrasonics model W375) with a 1 cm probe for 3×1 minutes (pulsed) on ice. Lysed cell material is removed by centrifugation (12,000×g, 15 minutes) and the clarified supernatant applied to glutathione-sepharose resin (Pharmacia).

Glutathione-Sepharose Affinity Chromatography

Twelve ml of a 50% glutathione sepharose-PBS suspension is added to 200 ml clarified supernatant and incubated batchwise for 30 minutes at room temperature. The resin is collected by centrifugation (600×g, 5 min) and washed with 2×150 ml PBS/1% Triton X-100, followed by 4×40 ml PBS. To cleave the p38 kinase from the GST-p38 fusion protein, the glutathione-sepharose resin is resuspended in 6 ml PBS containing 250 units thrombin protease (Pharmacia, specific activity >7500 units/mg) and mixed gently for 4 hours at room temperature. The glutathione-sepharose resin is removed by centrifugation (600.times.g, 5 min) and washed 2×6 ml with PBS. The PBS wash fractions and digest supernatant containing p38 kinase protein are pooled and adjusted to 0.3 mM PMSF.

Mono Q Anion Exchange Chromatography

The thrombin-cleaved p38 kinase is further purified by FPLC-anion exchange chromatography. Thrombin-cleaved sample is diluted 2-fold with Buffer A (25 mM HEPES, pH 7.5, 25 mM beta-glycerophosphate, 2 mM DTT, 5% glycerol) and injected onto a Mono Q HR 10/10 (Pharmacia) anion exchange column equilibrated with Buffer A. The column is eluted with a 160 ml 0.1 M–0.6 M NaCl/Buffer A gradient (2 ml/minute flowrate). The p38 kinase peak eluting at 200 mM NaCl is collected and concentrated to 3–4 ml with a Filtron 10 concentrator. (Filtron Corp.).

Sephacryl S100 Gel Filtration Chromatography

The concentrated Mono Q- p38 kinase purified sample is purified by gel filtration chromatography (Pharmacia HiPrep 26/60 Sephacryl S100 column equilibrated with Buffer B (50 mM HEPES, pH 7.5, 50 mM NaCl, 2 mM DTT, 5% glycerol)). Protein is eluted from the column with Buffer B at a 0.5 ml/minute flowrate and protein is detected by absorbance at 280 nm. Fractions containing p38 kinase (detected by SDS-polyacrylamide gel electrophoresis) are pooled and frozen at −80° C. Typical purified protein yields from 5 L E. coli shake flasks fermentations are 35 mg p38 kinase.

In Vitro Assay

The ability of compounds to inhibit human p38 kinase alpha is evaluated using two in vitro assay methods. In the first method, activated human p38 kinase alpha phosphorylates a biotinylated substrate, PHAS-I (phosphorylated heat and acid stable protein-insulin inducible), in the presence of gamma ³²P-ATP (³²P-ATP). PHAS-I is biotinylated prior to the assay and provides a means of capturing the substrate, which is phosphorylated during the assay. p38 Kinase is activated by MKK6. Compounds were tested in 10 fold serial dilutions over the range of 100 μM to 0.001 μM using 1% DMSO. Each concentration of inhibitor is tested in triplicate.

All reactions are carried out in 96 well polypropylene plates. Each reaction well contains 25 mM HEPES pH 7.5, 10 mM magnesium acetate and 50 μM unlabeled ATP. Activation of p38 is required to achieve sufficient signal in the assay. Biotinylated PHAS-I is used at 1–2 μg per 50 μl reaction volume, with a final concentration of 1.5 μM. Activated human p38 kinase alpha is used at 1 μg per 50 μl reaction volume representing a final concentration of 0.3 μM. Gamma ³²P-ATP is used to follow the phosphorylation of PHAS-I. ³²P-ATP has a specific activity of 3000 Ci/mmol and is used at 1.2 μCi per 50 μl reaction volume. The reaction proceeds either for one hour or overnight at 30° C.

Following incubation, 20 μl of reaction mixture is transferred to a high capacity streptavidin coated filter plate (SAM-streptavidin-matrix, Promega) prewetted with phosphate buffered saline. The transferred reaction mix is allowed to contact the streptavidin membrane of the Promega plate for 1–2 minutes. Following capture of biotinylated PHAS-I with ³²P incorporated, each well is washed to remove unincorporated ³²P-ATP three times with 2M NaCl, three washes of 2M NaCl with 1% phosphoric, three washes of distilled water and finally a single wash of 95% ethanol. Filter plates are air-dried and 20 μl of scintillant is added. The plates are sealed and counted.

A second assay format is also employed that is based on p38 kinase alpha induced phosphorylation of EGFRP (epidermal growth factor receptor peptide, a 21 mer) in the presence ³³P-ATP. Compounds are tested in 10 fold serial dilutions over the range of 100 μM to 0.001 μM in 1% DMSO. Each concentration of inhibitor is tested in triplicate. Compounds were evaluated in 50 μl reaction volumes in the presence of 25 mM Hepes pH 7.5, 10 mM magnesium acetate, 4% glycerol, 0.4% bovine serum albumin, 0.4 mM DTT, 50 μM unlabeled ATP, 25 μg EGFRP (200 μM), and 0.05 μCi ³³P-ATP. Reactions are initiated by addition of 0.09 μg of activated, purified human GST-p38 kinase alpha. Activation is carried out using GST-MKK6 (5:1,p38:MKK6) for one hour at 30° C. in the presence of 50 μM ATP. Following incubation for 60 minutes at room temperature, the reaction is stopped by addition of 150 μl of AG 1×8 resin in 900 mM sodium formate buffer, pH 3.0 (1 volume resin to 2 volumes buffer). The mixture is mixed three times with pipetting and the resin is allowed to settle. A total of 50 μl of clarified solution head volume is transferred from the reaction wells to Microlite-2 plates. 150 μl of Microscint 40 is then added to each well of the Microlite plate, and the plate is sealed, mixed, and counted.

Preferred compounds of the invention exhibit IC50 values of 25 micromolar or less. More preferred compounds of the invention exhibit IC50 values of 10 micromolar or less. Even more preferred compounds of the invention exhibit IC50 values of 5 micromolar or less. Especially preferred compounds of the invention exhibit IC50 values of 1 micromolar or less.

Some representative examples with IC50 values are shown below.

<5.00 TNF Cell Assays Method of Isolation of Human Peripheral Blood Mononuclear Cells:

Human whole blood is collected in Vacutainer tubes containing EDTA as an anticoagulant. A blood sample (7 ml) is carefully layered over 5 ml PMN Cell Isolation Medium (Robbins Scientific) in a 15 ml round bottom centrifuge tube. The sample is centrifuged at 450–500×g for 30–35 minutes in a swing out rotor at room temperature. After centrifugation, the top band of cells are removed and washed 3 times with PBS w/o calcium or magnesium. The cells are centrifuged at 400 times gravity for 10 minutes at room temperature. The cells are resuspended in Macrophage Serum Free Medium (Gibco BRL) at a concentration of 2 million cells/mi.

LPS Stimulation of Human PBMs

PBM cells (0.1 ml, 2 million/ml) are co-incubated with 0.1 ml compound (10–0.41 μM, final concentration) for 1 hour in flat bottom 96 well microtiter plates. Compounds are dissolved in DMSO initially and diluted in TCM for a final concentration of 0.1% DMSO. LPS (Calbiochem, 20 ng/ml, final concentration) is then added at a volume of 0.010 ml. Cultures are incubated overnight at 37° C. Supernatants are then removed and tested by ELISA for TNF-a and IL1-b. Viability is analyzed using MTS. After 0.1 ml supernatant is collected, 0.020 ml MTS is added to remaining 0.1 ml cells. The cells are incubated at 37° C. for 2–4 hours, then the O.D. is measured at 490–650 nM.

Maintenance and Differentiation of the U937 Human Histiocytic Lymphoma Cell Line

U937 cells (ATCC) are propagated in RPMI 1640 containing 10% fetal bovine serum, 100 IU/ml penicillin, 100 μg/ml streptomycin, and 2 mM glutamine (Gibco). Fifty million cells in 100 ml media are induced to terminal monocytic differentiation by 24 hour incubation with 20 ng/ml phorbol 12-myristate 13-acetate (Sigma). The cells are washed by centrifugation (200×g for 5 min) and resuspended in 100 ml fresh medium. After 24–48 hours, the cells are harvested, centrifuged, and resuspended in culture medium at 2 million cells/ml.

LPS Stimulation of TNF Production by U937 Cells

U937 cells (0.1 ml, 2 million/ml) are incubated with 0.1 ml compound (0.004–50 μM, final concentration) for 1 hour in 96 well microtiter plates. Compounds are prepared as 10 mM stock solutions in DMSO and diluted in culture medium to yield a final DMSO concentration of 0.1% in the cell assay. LPS (E coli, 100 ng/ml final concentration) is then added at a volume of 0.02 ml. After 4 hour incubation at 37° C., the amount of TNF-alpha released in the culture medium is quantitated by ELISA. Inhibitory potency is expressed as IC50 (μM).

Rat Assay

The efficacy of the novel compounds in blocking the production of TNF also is evaluated using a model based on rats challenged with LPS. Male Harlen Lewis rats [Sprague Dawley Co.] are used in this model. Each rat weighed approximately 300 g and is fasted overnight prior to testing. Compound administration is typically by oral gavage (although intraperitoneal, subcutaneous and intravenous administration are also used in a few instances) 1 to 24 hours prior to the LPS challenge. Rats are administered 30 μg/kg LPS [salmonella typhosa, Sigma Co.] intravenously via the tail vein. Blood is collected via heart puncture 1 hour after the LPS challenge. Serum samples are stored at −20° C. until quantitative analysis of TNF-alpha by Enzyme Linked-Immuno-Sorbent Assay (“ELISA”) [Biosource]. Additional details of the assay are set forth in Perretti, M., et al., Br. J. Pharmacol. (1993), 110, 868–874, which is incorporated by reference in this application.

Mouse Assay

Mouse Model of LPS-Induced TNF Alpha Production

TNF alpha is induced in 10–12 week old BALB/c female mice by tail vein injection with 100 ng lipopolysaccharide (from S. Typhosa) in 0.2 ml saline. One hour later mice are bled from the retroorbital sinus and TNF concentrations in serum from clotted blood are quantified by ELISA. Typically, peak levels of serum TNF ranged from 2–6 ng/ml one hour after LPS injection.

The compounds tested are administered to fasted mice by oral gavage as a suspension in 0.2 ml of 0.5% methylcellulose and 0.025% Tween 20 in water at 1 hour or 6 hours prior to LPS injection. The 1 hour protocol allows evaluation of compound potency at Cmax plasma levels whereas the 6 hour protocol allows estimation of compound duration of action. Efficacy is determined at each time point as percent inhibition of serum TNF levels relative to LPS injected mice that received vehicle only.

Induction and Assessment of Collagen-Induced Arthritis in Mice

Arthritis is induced in mice according to the procedure set forth in J. M. Stuart, Collagen Autoimmune Arthritis, Annual Rev. Immunol. 2:199 (1984), which is incorporated herein by reference. Specifically, arthritis is induced in 8–12 week old DBA/1 male mice by injection of 50 μg of chick type II collagen (CII) (provided by Dr. Marie Griffiths, Univ. of Utah, Salt Lake City, Utah) in complete Freund's adjuvant (Sigma) on day 0 at the base of the tail. Injection volume is 100 μl. Animals are boosted on day 21 with 50 μg of CII in incomplete Freund's adjuvant (100 μl volume). Animals are evaluated several times each week for signs of arthritis. Any animal with paw redness or swelling is counted as arthritic. Scoring of arthritic paws is conducted in accordance with the procedure set forth in Wooley et al., Genetic Control of Type II Collagen Induced Arthritis in Mice: Factors Influencing Disease Suspectibility and Evidence for Multiple MHC Associated Gene Control., Trans. Proc., 15:180 (1983). Scoring of severity is carried out using a score of 1–3 for each paw (maximal score of 12/mouse). Animals displaying any redness or swelling of digits or the paw are scored as 1. Gross swelling of the whole paw or deformity is scored as 2. Ankylosis of joints is scored as 3. Animals are evaluated for 8 weeks. 8–10 animals per group are used.
